The police officer who killed Philando Castile during a traffic stop has turned himself into police, one day after he was charged for the deadly shooting.

St Anthony Police Officer Jeronimo Yanez handed himself in at the Ramsey County jail in Minnesota on Thursday.

The cop was charged with three felony counts - second-degree manslaughter and two counts of dangerous discharge of a firearm - on Wednesday.

Police Officer Jeronimo Yanez (left, in his mugshot, and right, in uniform), who killed Philando Castile during a traffic stop has turned himself into police, one day after he was charged for the deadly shooting

He plans to plead not guilty to the charges, the Star Tribune reports.

Ramsey County Sheriff Department spokesman Sgt. John Eastham told the newspaper the cop had been 'summons booked' - which means he was released immediately without having to post bond after his mugshot was taken and he was processed.

Yanez shot Castile, 32, seven times in Falcon Heights, a suburb of St Paul, on July 6 while his girlfriend and her four-year-old daughter were sat in the car.

The shooting created headlines around the world because Castile's girlfriend, Diamond Reynolds, live streamed the moments after the shooting on Facebook.

There were widespread protests after the shooting as a result of the footage.

It was revealed for the first time what Castile's final words were moments before Reynolds started filming.

'I wasn't reaching for it,' Castile said seconds after he was hit with the bullets that would kill him.

PROSECUTOR RECOUNTS CASTILE'S LAST MOMENTS

Officer Yanez asked Castile to produce his driver's license and proof of insurance. Castile first provided him with his insurance card.

Castile then, calmly, and in a non-threatening manner, informed Officer Yanez, 'sir, I have to tell you that I do have a firearm on me.'

Before Castile completed the sentence, Officer Yanez interrupted and calmly replied, 'okay' and placed his right hand on the holster of his own, holstered, gun.

Officer Yanez then said, 'okay, don't reach for it, then.'

Castile tried to respond but was interrupted by Officer Yanez, who said, 'don't pull it out.'

Castile responded, 'I'm not pulling it out,' and Reynolds also responded by saying, 'he's not pulling it out.'

Then Officer Yanez screamed, 'don't pull it out!' and quickly pulled his own gun with his right hand while he reached inside the driver's side window with his left hand.

Officer Yanez pulled his left arm out of the car, and then fired seven shots in rapid succession into the vehicle.

The seventh and final shot was fired at 9:06 and two seconds p.m.

After the final shot, Reynolds frantically yelled, 'you just killed my boyfriend!'

Philando Castile moaned and uttered his final words: 'I wasn't reaching for it.'

To which Reynolds loudly said, 'he wasn't reaching for it.'

Before Reynolds completed her sentence, Officer Yanez again screamed, 'don't pull it out!'

Reynolds responded by saying, 'he wasn't.'

'The mere mention or presence of a firearm alone cannot justify the use of deadly force,' he added.'Unreasonable fear cannot justify the use of deadly force.

'Unreasonable fear cannot justify the use of deadly force.'

Choi went on to say evidence proves Castile, an elementary school cafeteria worker, never tried to remove the gun that was inside the front-right pocket of his shorts, and that Reynolds' Facebook video shows that the 32-year-old had not been resisting arrest or had any criminal intent.

Yanez's attorney, Tom Kelly, argued his client had been reacting to the presence of a gun, and insisted one reason Yanez pulled Castile over was because he thought he looked like an armed robbery suspect.

The cop is the first officer to have been charged in more than 150 police-involved deaths in Minnesota since 2000.

Yanez is due to make his first appearance in court on Friday.

If convicted, he could face 10 years in prison and a $20,000 fine.

TIMELINE OF PHILANDO CASTILLE'S SHOOTING AND AFTERMATH

July 6: Castile is fatally shot after Yanez stops his car in Falcon Heights. Castile's girlfriend livestreams the aftermath on Facebook and the widely shared video draws protesters to the scene.

July 7: Protesters converge overnight at Gov. Mark Dayton's official residence in nearby in St. Paul. The Democratic governor says he doesn't think the shooting would have happened if Castile had been white. More than 1,000 people gather that evening at the school where Castile worked, and hundreds walk back afterward to the governor's residence.

July 8: Ramsey County Attorney John Choi says he'll decide later whether he or a grand jury will decide on any charges against Yanez.

July 9: Attorney Thomas Kelly says Yanez was reacting to the presence of the gun when he opened fire on Castile. He says the shooting had nothing to do with race. Police use chemical irritants to clear rock-and-bottle-throwing demonstrators from Interstate 94 in St. Paul. Officers arrest over 100 people. Police say 21 officers were hurt; none seriously.

July 10: The governor condemns the shutdown of I-94 as 'unlawful and extremely dangerous.'

July 11: Forty-six people are charged with rioting for the I-94 protest. Kelly says Yanez thought Castile looked like 'a possible match' for a suspect in a recent armed robbery.

July 12: Castile's family says they will file a lawsuit in his death.

July 13: Police arrest 42 protesters who block traffic on Interstate 35W near downtown Minneapolis during the morning rush.

July 14: A funeral for Castile at the St. Paul Cathedral draws thousands of mourners.

July 26-27: Police arrest 69 protesters outside the governor's residence as officers clear out the blocked street in front of the mansion.

July 29: Choi adds former U.S. Department of Justice attorney and former Hamline University Law School Don Lewis, who is black, to his team as a special prosecutor in a bid to enhance trust in the results of the investigation.

August 24: The St. Anthony Police Department says it put Yanez back on administrative leave after he had briefly returned to limited duty, citing 'concerns and other feedback from the community.'

September 28: The state Bureau of Criminal Apprehension says it has completed its investigation and turned over its findings to Choi.

November 16: Prosecutors announce plans to provide an update about their investigation. The announcement comes one day after the anniversary of the high-profile killing by police of another black man in Minnesota, Jamar Clark in Minneapolis. No charges have been filed in that case.
